Peggy K’s Brain Power Smoothie: When I have been feeling sluggish and foggy, I reach for this smoothie. It’s loaded with antioxidants to help manage inflammation. It starts with a base of antioxidant-rich berries: blackberries and blueberries. Then I add fresh turmeric—a root veggie that belongs to the ginger family, but most of us know it best in its powdered form as a bright yellow spice. Its active flavonoid, curcumin, is a powerful antioxidant.
